Air Monitoring Information

Charter Environmental continues to monitor the four sampling locations
during the 8 -hour day for dust particulates.

The four perimeter sampling stations are set up in the following
locations:

Station 1 -- Site fence gate on Pleasant Street
Station 2 -- Site fence on east end of Church Street
Station 3 -- Site fence on bike path at Tripp Street
Station 4 -- Site fence at bike path near Adams Street

The dust particulate and asbestos sampling results recorded at
each station every hour in a monitoring log. These results are
compared to the action levels established for each parameter. These
action levels are concentrations at which it is deemed unsafe and
work would have to stop.

Results of the air monitoring data has shown that exposure of
unsafe conditions to workers in the exclusion zone and to the public
is well below the actions levels.

Dust Particulate Monitoring -- The National
Ambient Air Quality standard for particulates is 150 micrograms
per cubic meter (µg/m3) over an average of 24
hours. This value will be used, however, for a one hour period.
Heavy metal presence is factored into determination of this action
level. The average levels recorded at
these locations range from 0 to 0.020 (µg/m3), with most readings
valued at zero. The maximum level for this week is also recorded
and ranges from 0.000 to 1.034 (µg/m3).

Asbestos Monitoring - Asbestos monitoring has
been discontinued. All abatement measures have been completed,
therefore monitoring is no longer required.

Actual Data - Below are tables showing the average
and maximum dust particulate readings taken at each sampling location
during the week of November 3 through November 9.
